Hello, coder! Today, we will explore techniques in Go that help maintain backward compatibility while adding new features to your software.

Today, our journey comprises:

• Understanding Go-centric methodologies for backward compatibility.
• Utilizing interfaces and different function names.
• Applying these techniques to practical problems.

Let's dive in!

Backward compatibility ensures that new enhancements do not interfere with existing software features. In Go, achieving this often involves using interfaces, function variations, or different function names, rather than method overloading.

Interfaces in Go allow for flexible and adaptable function design. By defining behaviors as interfaces, you can implement new functionality without altering existing code. Another strategy is using variations in function names to add new features while maintaining the originals, much like having distinct tools for specific tasks in a toolbox.

Consider using interfaces for a Greet functionality that adjusts as per user requirements:

By implementing different structures for varying greetings, Go ensures backward compatibility and facilitates new feature implementations without disrupting existing code.
